In 1971, wild horses and burros were found roaming across 53.8 million acres of Herd Areas (HAs), of which 42.4 million acres were under the Bureau of Land Management’s (BLM’s) jurisdiction. Today the BLM manages wild horses and burros in subsets of these HAs, known as Herd Management Areas (HMAs) that comprise 31.6 millionacres, of which 26.9 million acres are under BLM management.

The Antelope Hills HMA encompasses nearly 159,000 acres, of both public and private lands. The AML for this HMA is 60-82 adult horses. The area is located approximately 15 miles south/southeast of Atlantic City, Wyo. Elevations in the HMA range from 7,100 to 7,250 feet along Cyclone Rim and it is bisected by the Continental Divide National Scenic Trail. The area receives five to seven inches of precipitation annually. Predominate vegetation type is sagebrush/grass and riparian zones are infrequent but very important to wild horses, wildlife, and livestock. The topography ranges from rolling flatlands south of Cyclone Rim, uplifted ridges along Cyclone Rim, and abrupt rocky zones of the Granite Rocks area of the Antelope Hills, interspersed with rolling lands north of the rim to the Sweetwater River. These horses spend much of their summer in the Granite Rocks Region of the HMA. This HMA has genetic markers that would reflect a similarity to the New World Spanish horse breeds. Sweeping views of the southern Wind River Mountain Range can be seen to the west of this HMA. This HMA is truly in the “middle of nowhere” with scenic vistas throughout.
